Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of antiviral and anticancer agents. Its structure allows for functionalization at multiple sites, making it valuable in medicinal chemistry for building pyrimidine-based drug candidates. It is also employed in the preparation of agrochemicals and dyes due to its electron-deficient aromatic core, which facilitates nucleophilic substitution reactions. Additionally, it serves as a building block in the creation of heterocyclic compounds used in materials science and organic electronics.
